Oxidized glutathione (GSSG) is the disulfide-linked dimer formed when two molecules of reduced glutathione (GSH) are oxidised and joined via a disulphide bond. Together, GSH and GSSG constitute a critical cellular redox couple that helps regulate oxidative balance, signalling pathways and detoxification processes. The ratio of GSH to GSSG is a widely used indicator of cellular oxidative stress.
Glutathione Oxidized GSSG from TCS INDUSTRIES LIMITED is provided as a high-purity material suitable for biochemical research, redox studies, analytical standards and specialised formulations. In laboratories, GSSG is commonly used to calibrate assays, stress-test antioxidant systems and study protein glutathionylation and redox regulation.
TCS GROUP also supplies the corresponding reduced form,
allowing researchers and formulators to work with the complete redox pair from a single, consistent supplier. This is especially valuable in applications where the dynamic interconversion between GSH and GSSG is central to the mechanism of action or analytical read-out.
Beyond research, GSSG can be incorporated into advanced cosmetics and nutraceuticals that focus on redox balance and cellular defence. It pairs well with other stress-protection actives offered by TCS INDUSTRIES LIMITED, such as:
- Ectoin – an extremolyte that stabilises proteins and membranes under environmental stress, complementing GSSG’s role in redox-related protection.
- Ergothioneine – a thiol antioxidant that accumulates in high-stress tissues, often positioned alongside glutathione-based ingredients in “cell protection” or “longevity” formulations.
Where GSSG is used as an intermediate or component in more complex active systems, it aligns with the TCS
category, highlighting its relevance in upstream synthesis and advanced ingredient design.
With strict control over purity, trace impurities and stability, Glutathione Oxidized GSSG from TCS INDUSTRIES LIMITED gives researchers and product developers a reliable tool for redox calibration, mechanistic studies and next-generation antioxidant formulations, fully supported by the company’s expertise in peptides, antioxidants and pharmaceutical-grade ingredients.
